我正在使用以下代码发出 Get 请求：

            TheRequest = (HttpWebRequest)WebRequest.Create(aURL);
            TheRequest.Method            = "GET";
            TheRequest.CookieContainer   = TheCookies;
    TheRequest.UserAgent         = GetUserAgent();
    TheRequest.KeepAlive         = false;
    TheRequest.Timeout       = 20000;
            TheRequest.ReadWriteTimeout  = 20000;
    TheRequest.AllowAutoRedirect = true;
    TheRequest.Headers.Add("Accept-Language", "en-us");
            TheResponse = (HttpWebResponse)TheRequest.GetResponse();
            TheResponseString = new StreamReader(TheResponse.GetResponseStream(), Encoding.ASCII).ReadToEnd();

在此之后，我按如下方式获取 cookie：

string theCookieHeader = TheResponse.Headers[HttpResponseHeader.SetCookie];

然后我将字符串处理为正确的 cookie 格式，并将其放入 cookie 容器中，以便在下一个 POST 请求中提供。从响应字符串 (TheResponseString) 我创建正确的 Post 数据和来自 cookiecontainer 的 cookie。

我的 POST 请求代码如下：

                  TheRequest = (HttpWebRequest)WebRequest.Create(aURL);
                  TheRequest.Method            = "POST";
                  TheRequest.CookieContainer   = TheCookies;
          TheRequest.UserAgent       = GetUserAgent();
          TheRequest.KeepAlive       = false;          
                  TheRequest.Timeout             = 20000;
                  TheRequest.ReadWriteTimeout  = 20000;
          TheRequest.AllowAutoRedirect = true;
          TheRequest.ContentType       = "application/x-www-form-urlencoded";
          TheRequest.Headers.Add("Accept-Language", "en-us"); 
                  byte[] bytes = Encoding.ASCII.GetBytes(aPostDataString);
          TheRequest.ContentLength = bytes.Length;
          Stream oStreamOut = TheRequest.GetRequestStream();
          oStreamOut.Write(bytes,0,bytes.Length);
          oStreamOut.Close();

                  TheResponse = (HttpWebResponse)TheRequest.GetResponse();

                  TheResponseString = new StreamReader(TheResponse.GetResponseStream(),                            Encoding.ASCII).ReadToEnd();

现在的问题是我有两个网站，它们是合作伙伴网站，它们的一切都一样（看起来，但如果你有任何疑问，请告诉我），但是对于一个网站它工作正常，而对于另一个网站它给出了响应字符串网站错误页面。

请帮我看什么来诊断问题。

我有类似的问题。尝试从请求中保存 cookie，在您得到响应甚至更好之后，将此代码放入finally块中。为 TheRequest.Host 运行一次，为第二个站点的主机运行第二次。还要看看你是否需要 http 或 https

foreach (Cookie c in TheRequest.CookieContainer.GetCookies(new Uri("http://" + TheRequest.Host)))
{
   TheCookies.SetCookies(new Uri("http://" + TheRequest.Host), c.Name + "=" + c.Value);
}
